I have a few quads. A few "original" Revolution, some "replicas" (in improved version), a few Detox and three Djinn.
The Djinn are by far the most flown quads. I like the colour design/layout, the quality of the craftsmanship, the innovative details and the flying characteristics.
Another advantage is the always good helpfulness and support from @John Barresi. In the quad (!) sector, in my opinion, only Los Hermanos (-> Detox) are as great.
Disadvantages? Hmmm... I don't know any!
Difference to other quads? I mainly fly Djinn and Detox. Djinn on short lines. Detox on long lines. But that's more subjective and my choice is based on terrain and mood.
